I am still stuck on this. Has anyone successfully done this (foreach loop
with three groups)? It seems like a basic use case to me? I'm sure I'm
just missing something little. I'll try and post a simple example later...
Thanks in advance,
Justin

Subject: RE: Foreach loops with groups
sendRequest appears once for every row in an html table. I want to exercise
(an HTTP sample) for every link in the table. Therefore I want to extract
three values for each call to sendRequest and pass those into an HTTP
request.
Docs:
"By omitting the "_" separator, the ForEach Controller can be used to loop
through the groups by using the input variable refName_g, and can also loop
through all the groups in all the matches by using an input variable of the
form refName_${C}_g, where C is a counter variable."
This is confusing to me? To access group 1 of a variable in a for each loop
what do I do? ${synopticDataOut_${C}_g1}? A variable inside a variable
doesn't seem to work. What is C? Is that the name of a counter that I
added as a child of the for each loop? That doesn't seem to work either.
Or maybe it's an implicit counter? Also, by omitting the "_" separator the
for each loop is never entered, (see below).
I appreciate your help,
Justin

You probably don't need .* before and after.

Do you really want all matches?
How many times does sendRequest appear?

OK.

ForEach only sets _one_ variable, i.e. ${synopticDataOut}
> ${synopticDataOut} becomes 11479239
ForEach sets ${synopticDataOut} to ${synopticDataIn_1}, ${synopticDataIn_2},
etc. These are the values of $1$ for each match. Is this what you wanted?

These are wrong - ForEach only sets ${synopticDataOut}

No, it won't work.
See above and the documentation for RegexExtractor and ForEach.
